Who developed the first "standalone" Smart Camera that contained a DSP or Microprocessor for decision making?

By "smart" let's say that we're describing a machine vision device that has the acquisition, possibly optics and illumination, and processing components and software along with suitable industrial I/O to communicate results, all packaged in a single integrated component. One also might have to limit it to devices that were commercially "viable": a few components and custom devices like this were around in the late 1980's or before but were either not marketed or did not achieve broad success. To my knowledge, no manufacturer or person claims to have had the world's first "smart camera". However, Dickerson Vision Technologies introduced a component that I worked with which indeed met all of the definitions above as early as 1990/91 called the DVT smart camera. Likely there's something earlier. (Allen-Bradley had the VIM much earlier but that was a tethered "smart" camera system.) It would be interesting to hear other comments on this.
